Hello both, I am researching Whight and Mann, the Ipswich company mentioned by David. I found George Whight and Aldridge Mann were partners and that Aldridge Mann married Jane Foster, the only daughter of John Whight, a builder in Ipswich on April 18th 1851. I believe John was the father of George. I assume Jane must have been widowed or divorced. The Mann family appears to have ended up in Kenya. Aldridge died in November 1876 and I think George died in 1906. Hope the info helps you further. I have a Whight and Mann sewing machine!
